Patent GB-756635-A (GB)
Abstract: 756,635. Variable resistances. CLOBEUNION, Inc. Aug. 5, 1954, No. 22809/54. Class 37. A variable resistor has a rotatable shaft mounted in a housing and in a cylindrical section of a front plate which is secured to the housing, the plate being mounted in an opening in a panel with a locking bar projecting from it on one side and a spring finger on the other side of the panel. In this way the front plate provides a front bearing for the shaft, a mounting for the resistor and a connection for the non- current carrying parts of it. Figs. 1 and 2 show parts of a variable radio type resistor of which the resistance element, collecting ring and wiper (not shown), are of conventional type. The rotatable control member has a shaft 20 with a rearward projection 21 which is supported in the central opening 12 of metal housing 10; tongues 14 on which engage with notches on mounting panel 40 and a stop 18 of which limits the rotation of the control member by engagement with a stop 26 on shoe 22. A thrust ring 28 bears against the inner wall of housing 10. Wiper 34 has spring fingers 36 which connect with the resistance element (not shown) and collecting ring contactor 38 which runs on a collecting ring (not shown). An insulating panel 40 carries terminals 42, 44 and has notches 4 into which the tongues 14 and prongs 16 fit. The metal front plate 48 has a cylindrical section 50 and has a forward end which forms a bearing 54 for the front end of shaft 20, the plate is looked to housing 10 by tabs 62 which fit in the spaces between tongues 14 and prongs 16, the tabs 62 also space terminals 42, 44 from the panel. The plate 48 is mounted on panel 63 and itself provides a panel-mounting for the resistor by means of the ears 52 which are sprung into engagement with the front of the panel and spring fingers 60 which engage with the rear. One prong 16 may fit into a slot in panel 63 to prevent rotation of the resistor relative to it. In a modification shown in Fig. 3 a rear bearing for shaft 20 is provided by an inwardly-directed flange 66 on housing 64 which fits into an opening 68 on the rotatable control member which has a thrust ring 70. The control member, excluding the wiper, may be moulded in a single piece of plastic.

Title: A process for desulphurising sulphur-containing active carbon
IPC: C01B31/08
Filed: 1978-10-26
Abstract: Sulphur-containing active carbon is desulphurised by treating the active carbon with water in the presence of oxygen at a temperature from room temperature to the boiling point of the suspension of active carbon in water. Preferably the oxygen is introduced into the active carbon suspension in the form of a mixture with inert gases, in pure form or in the form of air. The invention allows sulphur to be removed from active carbon made from relatively inexpensive starting materials such as carbonised lignite, petroleum coke or mineral coke.
Patent GB-2013648-A (GB)
Title: A Process for the Manufacture of Cement
IPC: C04B7/36
Filed: 1978-11-02
Abstract: The invention relates to the manufacture of an active belite cement which behaves in the manner of Portland cement at a calcium rating of between 75 and 85, the heating and deacidifying process up to 950 DEG C being unimportant as far as the compressive strength of the cement is concerned, as is the heating process from 950 DEG C up to the sintering temperature which lies within the range between 1350 DEG C and 1450 DEG C. The clinker is subjected to mechanical activation, for example, in a ball mill, either subsequent to grinding in the ball mill or in place thereof, or the active condition of the belite is reached by the cooling process. Cooling is effected by quenching the clinker or tempering it or by gradual cooling, whereby the cooling gradient should be >500 cal/min in the temperature range between from 1350 DEG C to 1250 DEG C (upper limit) and from 1000 DEG C to 800 DEG C (lower limit).

Title: Auto-tracking control systems for apparatus for reproducing video signals
IPC: G11B5/588
Filed: 1979-03-02
Abstract: An auto-tracking control system for use in apparatus for reproducing a video signal recorded in successive parallel tracks on a recording medium, includes a magnetic head chip 25 for scanning the recording medium in successive scanning paths to reproduce the video signal recorded thereon, and a deflectable head support for supporting and deflecting the head chip 25, the deflectable head support having two deflectable portions 21 and 22 made of electro-mechanical transducing material such as piezo-ceramic material in the form of bi-morph leaves, and responsive to electrical signals of substantially different vibrational frequencies.

Patent GB-2062238-A (GB)
Title: An impedance measuring system
IPC: G01R27/02
Filed: 1979-10-15
Abstract: In an impedance measuring system e.g. for detecting the presence of water, ice or other conductive material or liquid the probes are isolated from the operating supply. The system comprises an alternating voltage supply which feeds a winding on an impedance transformer, the voltage supply being of a high impedance such that when a secondary winding of the transformer is loaded by say the presence of water between the probes then the alternating voltage supply is reduced. This reduction in voltage is measured and, when at a preset level, an output circuit is activated. This system allows for the electrical supply to the control circuit to be operated directly from mains electric supply without a mains isolating transformer, and to have isolated detector probes that can be earthed. Instead of using a transformer the probes may be connected to the supply via capacitors. <IMAGE>

Title: Improvements in or relating to restraining belts
IPC: B60R22/32
Filed: 1980-04-14
Abstract: A safety belt coupling device (10) has slots (13, 14) for attachment to two parts of a safety belt. The device is formed in two parts (11, 12) which engage one another by means of annular flanges (15, 16). The annular flanges (15, 16) are secured together by means of fusible material (20), for example a fusible metal, such that in normal operation the integrity of the device is maintained but that above a predetermined temperature the two parts of the device separate to release the safety belt. A spring (19) urges apart the two parts of the device to ensure release of the safety belt when the temperature rises above the predetermined temperature. Other examples of coupling devices released when a predetermined temperature is exceeded are disclosed. <IMAGE>

Title: Bottle filling head
IPC: B67C3/26
Filed: 1980-10-28
Abstract: The invention provides a filling head for introducing carbonated liquid into a bottle, comprising a hollow body 4 having at a lower end a nozzle 13, a liquid valve 11 in the body for controlling flow of liquid from within the body through the nozzle, a gas filling tube 14 extending through the liquid valve for admitting pressurised gas into the bottle, a counter-pressure tube 8 communicating with the filling tube and provided with a counter pressure 10, a snift valve for releasing gas from the nozzle, and, in the region of the liquid valve 11, firstly a shroud 20 which at least in the open condition of the liquid valve (as shown, Fig. 3) is positioned to provide an opening for the flow of liquid through the filling head, and secondly liquid throughflow passages 17. When liquid flow terminates on build-up of gas pressure within the headspace, liquid meniscuses are formed at passages 17. Shroud 20 helps prevent the breakdown of three meniscuses and so also the risk of overfilling. The shroud is preferably constructed and positioned so as to provide (i) a narrow annular gap 25 through which liquid can flow when the liquid valve is open, and (ii) an airtrap 28 in the vicinity of the nozzle. <IMAGE>

Title: Electrical connector with fuse carrier
IPC: H01R13/68
Filed: 1981-05-01
Abstract: An electrical connector has two connector members (e.g. an adaptor and a socket) each of which is provided with contact elements which connect when the two members are advanced into fully engaged position. One of the members (adaptor 1) has a movable fuse carrier 16 on it.
